| Title | Temporary Loss of Offsite Notification Sirens |
| Event Description | At 0935 on November 6, 2005, all offsite notification sirens for Crystal River Unit 3 were lost. One siren failed and sent a feedback signal which in turn disabled all remaining sirens. The failed siren was bypassed at 1124, thereby restoring the remaining 39 sirens to service. The failed siren will be repaired promptly. During the loss of siren function, backup means of notifying the public were available, including route alerting using local law enforcement and use of the Code Red autodialing system. This is reportable as an immediate notification (eight-hour report) in accordance with 10CFR50.72(b)(3)(xiii).
The siren system is maintained by the county. Compensatory measures for the remaining area is either: dispatching a police car, or fire truck, or using the Code Red autodialing system for the affected area. The licensee notified the NRC Resident Inspector. |
